BACKGROUND:Flashes are Purple Punchers whose hearts have been encased by ice, making it impossibly to catch them when the ice is covering their hearts. Vicent Van Gore got the idea for these ghosts when a Purple Puncher accidentally got stuck in the freezer and couldn't get out. It changed to a white color, and Vincent made more that had hearts surrounded by ice.
The only way to defeat these ghouls is by obtaining the Fire Element then shooting fire at them to get rid of the ice surrounding their hearts. Then they can be sucked up like a normal Purple Puncher.
